This pine is named for the spiny bracts on the outside of the cones. It is well adapted to fire because its crook-shaped lower trunk sends up new shoots if the upper trunk is killed by fire (Wikipedia contributors).

There is one small existing population. There were four populations from the late 1800s that no longer exist because their habitat has been eliminated but there's still one record from 1915 on Long Island that needs to be rechecked.
